\VILLIAM H. DOVVNING, OF GOODELL, PENNSYLVANIA SUCKEFt-ROD ADJUSTER.

SPECIFICATION forming part of Letters Patent; No. 364,226, dated J'u11e7, 1887.

Application filed August 3,1886. Serial No. 209,861. (No model.)

to be a full, clear, and exact description of the invention, such as will enable others skilled hollow screw, and the clamping-screw, which passes into the upper end of the collar or sleeve, all of which will be more fully described hereinafter.

The object of my invention is to produce an attachment for the suckenrods of deep wells, and in which the rods cannot become unscrewed. The rods can be raised and lowered without using ropes or bull-wheels. The rods can be turned and held in different positions to loosen the paraffinejn the tube, so that it will pump out and so that the adjuster need not be taken off the beam to pull the rods out of the well.

The accompanying drawing represents a vertical section of an apparatus embodying my invention.

A represents one end of the walking-beam, and B the trunnion,which is pivoted thereon in the usual manner. The end of the walkingbeam A is pronged or bifurcated, and upon the prongs are secured the boxes X, in which the trnnnions B partially rotate. The inner ends of the trunnions B are secured to the collar or sleeve Y,which is provided with the wings Z, which are internally screw-threaded, so as to make connection with thetrunnion, as shown. This collar is screw threaded internally through its vertical portion, so as to receive nally, as shown. Passing vertically through this collar Y is the hollow screw or sleeve 0, of suitable length, and upon which is placed the lock-nut D, which is provided withahandle upon one side, for the purpose of locking the screw or sleeve 0 in position, so that it cannot turn around. in the collar while the pump is at work. To the upper end of this hollow screw or sleeve 0 is rigidly secured the perforated cap or cover I which is provided with the handles G, and by means of which the sleeve or screw can be turned around for the purpose of adjusting it endwise through the trunnion B. Passing up through this hollow screw or sleeve 0 is the polish-rod H,which has a screw-coupling upon its lower end, connecting with the pumping-rod, and which has a screw-threaded tenon, I, formed upon its upper end. The shoulder formed upon the upper end of this rod H acts as astop to the rod, so that the tenon I only will project through the rod or cap F.

Screwed upon the thread of the tenon I is the sleeve J, which is provided with the handles L, so that the sleeve can be turned for the purpose oi'screwing it upon the tenon or removing it therefrom at will. Screwed into the top of this sleeve J is the clamping-screw O,which has the ring 1? formed upon its upper end. After the collar J has been screwed upon the tenon I the screw 0 is forced down into the collar, so as to bear against the tenon I, and thus prevent the tenon from turning and becoming loosened from the collar. This collarJ supports the polish-rod in position in the hollow screw or sleeve 0. By turning the screw or sleeve 0 it will be adjusted vertically through the trunnion B, and this rod H will be raised and lowered at the will of the operator. After the screw-rods have been detached from the polish-rod H and it is desired to remove the rod II, it is only necessary to remove the sleeve J, when the rod H can be detached entirely fromthe sleeve. By means of the construction here shown a single person can raise and lower the rods connected with the working valves in the well, without having to use a rope or any of the tools heretofore employed for that purpose, by simply standing upon the walking-beam and then turning the hollow screw or sleeve 0. In disconnecting the adjuster from the sucker-rods the adjuster need not be taken off from the beam, and thus asaving of time and labor is effected.

The polishrod being connected to the hollow screw or sleeve in the manner here shown, the rod cannot become unscrewed, so as to drop the valves together. The rods can also be turned and held in different positions, so as to loosen the parafline in the tubing, so that it can be pumped out.

Having thus described my invention, I claim- 1. The combination of thebeain A,theboxes X,mounted t118160ll,th6 trunnionsB, journaled in the boxes, and the internally-screw-threaded collar Y, connected to the trunnions at their inner ends,with the hollow screw rod or sleeve 0, which is screw-threaded externally, as shown.

2. The combination of the beam A,the boxes X, mounted thereon,the trunnions B, journaled in the boxes, the internallyserew-threaded collar Y, connected to the trunnions at their 20 V hollow screw rod or sleeve, the polish-rod, the

sleeve that screws upon the upper end of the polish-rod, and the clamping-screw, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM H. DOWNING.
